. Kaplan-Meier survival analysis of survival stratified by DKA and diabetes status. A) Death was more likely among patients who developed DKA (36.9% vs. 25.6%, P < 0.05) with a mean survival of 40.0 ± 1.9 days compared to patients who did not develop DKA (54.0 ± 1.9 days, P = 0.0008). B) Among patients with diabetes (n = 955), mean survival in patients with DKA was 40.0 ± 1.9 days compared to 40.6 ± 0.7 days in patients without DKA, with one-quarter of deaths occurring within 12 days (95% CI: 7–20) of admission in patients with DKA compared to 22 days (95% CI: 13–42) for patients without DKA (P = 0.03).
